The Star-Ledger's original endorsement in October drew attention for how backhanded of a compliment it was to Christie. Indeed, Moran wrote on Sunday that the editorial board's original decision came down to a close vote between the Republican Christie, who most of the board viewed as "the most overrated politician in the country," and Democrat Barbara Buono, who was perceived as not being ready to govern.

But despite his about-turn on Christie, Moran said he would still choose him over Sen. Rand Paul (R-Ky.) in a theoretical Republican presidential primary.

"And if you think that makes some sense, then you understand how excruciating the endorsement process can be," Moran wrote.

There's no love lost between the Ledger and the Christie administration. Moran wrote that Christie has "boycotted" the editorial board for "years" in an attempt to earn more favorable coverage.
